'IMPROVEMENT' IN DISTZLLING APPARATUS.

Specification forming part of Letters Patent No.125,463, dated April 9, 187

SPECIFICATION. To all whom t may concern:

Be it known that I, J ULIUS KUNZE, of Chatsworth, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Distillation;77 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying dra-win g making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.V

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

The accompanying drawing represents a vertical section of the-apparatus.

The object of my invention is to produce, by ordinary distillation, high wines or alcohol free from fusil or other disagreeable essential oil, and of any desirable strength. The nature of my invention consists iu the novel construction and arrangement of certain devices in an apparatus, as hereinafter described and claimed.

My mode or method of purification ofthe alcohol vapor as it comes out of the still mixed with fusil or other essential oil vapor an d aqueous vapor, and before it goes to the condenser, consists in subjecting the said vapor to a great mechanical friction and concussion, and lowering graduallyits temperature, thereby condensing a considerable quantity of oil vapor and aqueous vapor, and thus separating the same from alcohol vapor; then in suddenly lowering the temperature ofthe said vapor to such an eX tent as to precipitate or condense the Whole ot' ,the oily or aqueous vapor, or the most of it, and

return the same back to the still without condensing the alcohol vapor and finally in purifyin g the alcohol vapor from yet remaining traces of oily vapor or other impurities, by charcoal, before it is condensed and turned into high wines or alcohol.l

The appara-tus to perform all the above said operations is made ot' copper, and placed between the still S and condenser It of thefdistillery. It is placed on .a suit-able foundation` and consists of several pa-rts put up in the shape of a column, although any other suitable shape may be adopted.

A isa vessel or holder, connected with still S by pipe a to let in the alcohol vapor; also provided with faucet b to return the condensed oil or water back to the still S. B is acolumn yof any suitable size, divided by partitions into chambers. Partitions C C C are ot'dish-form, of the same diameter Vas the column, and secured to its walls. They are provided with openings o o o", for vapors to freely ascend, and with rims or borders rl d el, to prevent the condensed oil and water from passing through openings o o o, but to collect the same and pass them down through the pipes I) D secured totthe said partitions. Partitions E E E are of the shape of an inverted dish, for the purpose of easily conveying the drops ot' oil and water down, are of smaller diameter than column B, and are secured to the same by strips or staples f, leaving space F between wallsaud partitionsopen. Thealcohol vapor mixed with oily and aqueous vapors goes from the still S into vessel A, and from there ascends through opening o, spreads out right and left, goes around partition E, again through opening o', around partition E', and so on, until it reaches the top of column B, thus being subjected during the passage to a great friction and concussion, losing` caloric, and thereby lowering in temperature. rlhese frictions and reductions of temperature couden se a great deal offusil or other essential oil vapor, and also aqueous vapor, which, in a liquid state, are returned back to vessel A, falling in drops, for instance, on partition E, slide along it a-nd through space F, drip down onto partition C, then through pipes DD onto partition E', and so on, until they reach the lowest partition G and pipe g, through which they pass into vessel A, and from there can be returned to the still, it' desirable, every time the work stops, or ot'tener.

Thenumber of partitions in the column B depends upon the size of distilleryand the perfection of proposed puriticatiou ofthe alcohol vapor. l use from Athirty to fifty partitions, and

even more. The partitions should be always so shaped and arranged as to submit the vapors to a great friction against their surfaces, and to easily convey the condensed oily and aqueous vapors, in the shape of oil and water, back to the vessel A. rIheir shape and a 1angement denser, to precipitate or condense at once all the oil vapors or aqueous vapor ascending with alcoholvapor to the top ofthe column B, and thus separate them from the said alcohol vapor. The precipitator is a double Water-holder, having a passage between the two Waterholders for the vapors to pass. I is the inletpipe, through which water tills the spaces K K, and through the side pipes J J tills the spaces L L, from which, by the pipes l Z, it is conducted into and ills the space M, and then goes out by a discharge-pipe, m. Nis the passage for the alcohol vapor.` The Water in the precipitator is in constant motion. The oil vapors and aqueous vapors that ascended to the top ofthe column B With alcohol vapor Without being condensed, notv entering the passage N, trom a sudden reduction in temperature, rapidly condense, and in drops are conveyed down the column and returned to the vessel A, While the alcohol vapor passes on higher. P Pare the vessels for the charcoalholders Q, Q and steam-chambers T T. The alcohol vapor from the precipitator H passes by one or both pipes, qq, into the charcoal holders Q Q, perforated at the bottom, and, Working its way through the charcoal, becomes purified ot' traces ot fusil-oil or other impurities that perhaps were not condensed in the precipitator H, and thus, perfectly puried, passes through pipes r rinto the distillery condenser B, Where it is condensed into highwines or alcohol in the ordinary manner. Entering the vessel l? l) the alcohol vapor may partially condense, in which case it is conducted from there by pipes u uinto the column B, where it vaporizes again. T T are chambers to receive steam for the purpose of Warmin g the. alcohol vapor at the moment ot' its entering the charcoal, if desirable. t t are the inlet and outlet pipes for the steam, which when used is renewed constantly. 'Vaste steam is intended to be used for the purpose. By using steam here less steam will be required for the column and vessel A, or even in the still S.

It may be seen, from the above description of the apparatus and of the successive operations over the alcohol vapor, that by placing my apparatus between the still and the condenser in any distillery, an uninterrupted distillin g operation will be established, producing by au ordinary distillation high Wines or alcohol perfectly free from fusil or other essential oils or impurities, and of any desirable strength, while the quantity ot' Wines produced from a certain quantity of grain Will not be in the least diminished.

The apparatus can easily be adapted also for use in rect-ifying establishments.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-f `The combination of the vessel A and column B Wit-h the precipitator H, charcoal-ch ambers Q, Q, and steam-chambersT T, when constructed and arranged to operate substantially as and'for the purpose set forth.
